i know c,cpp and i want learn python..how many days or weeks or months its takes to learn ?

Answer 1

Considering that you already know C++ and C, then it should take you about 2-3 days for you to learn, if you choose to learn it through sololearn; But it will take you about a day to learn it if you can spend all your time into that.

Answer 2

If you alteady know C and C++, then Python should be easy to learn, and fun. Python has more builtin functions, and way more modules and frameworks.
If you only want to learn the syntax, then it should take about 10 to 20 hours, assuming you already know data structrures, functions and classes.
